I absolutely love these rugs! I got them for my small bathroom. They have a great color and are 100 cotton. There is no rubber backing to become cracked and sticky due to washing and drying often. They are soft and fluffy while at the same time, they weight enough to keep them put. They feel amazing under my feet! 
The tag does state that the rugs are flammable and should not be used near source of ignition. The microfiber rug they replaced had a similar warming about flammability. That hasnt been an issue in our home.
I intend to buy a set for the master bath. I recommend these awesome rugs.
